Excessive Sweating

Excessive Sweating





Hyperhidrosis is a disorder characterized by excessive uncontrollable sweating in excess of the amount required to regulate body temperature. It is estimated that 8.5 million people in the United States suffer from some form of hyperhidrosis. Primary hyperhidrosis has no discernible cause and may involve the axillae (armpits), palms (hands), soles (feet), face, and groin. Secondary hyperhidrosis has an underlying cause such as an endocrine disorder, secretory tumors, sympathetic nervous system disorder, or neurological/psychiatric disorders. You should talk to your doctor to determine if there is an underlying cause for your condition.



Botox is a natural, purified protein with the ability to temporarily block the secretion of the chemical that is responsible for “turning on” the body’s sweat glands. By blocking, or interrupting, this chemical messenger, botulinum toxin “turns off” sweating at the area where it has been injected. While sweating is an essential body function for temperature-control, the underarms house less than 2% of the body’s sweat glands. The treatment of these sweat glands has no effect on body temperature regulation and compensatory sweating (sweating on other body parts), has not shown itself to be a concern. Botox® is injected into the skin to treat the symptoms of severe underarm sweating (severe primary axillary hyperhidrosis) when medicines used on the skin (topical) do not work well enough.



  • The treatment areas will be wiped with a cleanser and alcohol
  • For underarms, please wear loose and comfortable clothing to prevent rubbing and chafing in the treatment area
  • For hands and feet, some clients find it helpful to take a mild analgesic (Tylenol) one hour prior to treatment
  • For underarms, hands and feet: ice, vibration or numbing spray may be applied to the skin to help with any discomfort during the treatment



  • BOTOX injections are made in the skin near the sweat glands responsible for perspiration and are administered using a very fine needle. Treatment time may take anywhere between 20 to 45 minutes, depending on the size of the injection site.



  • Do not apply pressure to/or massage the treatment area
  • Pinpoint bleeding may occur and will resolve quickly
  • Rarely, clients may develop mild bruising and or sensitivity around the injection site. This will resolve within the first week after treatment
  • Any immediate redness or swelling will subside within an hour
  • Your results will appear gradually over the period of 7-14 days
